I read a articale about keno machines. I played them on the internet here. at the game shacks of florida. They do well. I watch this afro -am women win very good for 2 hrs and hit for cash card of $1,000 for 2 hrs. She just kept changing the numbers when they hit. The articale say you have to play the same numbers for a long time. to get good result. I play looking for the sweepstakes to hit my machine. .5 cents a play.
